BUTTONHOLE MEASURING AND CUTTING MACHINE.

Specification of Letters Patent.

. Patented Aug. 26,1913.

Application filed September 20, 1912. Serial N 0. 721,475.

To all whom it may concern:

Be it known that I, ASHER LEVIN, a citi zen of the United States,residing at Baltimore city, State of Maryland, have invented new anduseful Improvements in Buttonhole Measuring and Cutting Machines, ofwhich the following is a specifi- U cation.

The invention has for its object the provision of a machine for cuttingbuttonholes in garments and embodying means for regularly spacing thecutters and for cutting H buttonholes of varying lengths to meet varyingconditions. The invention is designed to supply a machine of thecharacter hereinbefore stated which in its general organization issimple, effective in operation and easy of manipulation and adjustment.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the accompanying drawings, and pointed out inthe appended claims.

Referring to the drawings, forming a part of the specification, Figure lis a top plan view of a machine of the character stated embodying theinvention. Fig. 2 is a view of the machine inverted and as seen from thebottom side. Fig. 3 is a transverse section. Fig. 4 is an end view. Fig.5 is a detail view of the plate for supporting the .work againsttheaction of the cutters.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawings, by the samereference characters.

I The machine embodies a base 1 which is 4.0 hollow and has standards 2at opposite ends. A rod or bar 3 is supported at its ends in thestandards 2 and receives the cutters which are mounted thereon so as toreceive a twofold movement, the one for spacing and the other foradvancing to and moving away from the work. A plurality of cutters areprovided each being the substantial duplicate of the other. Each of thecutters consists of a head 4 having a socket 5 and an extension 6 towhich a blade 7 and a punch 9 are attached. The head 4: is notched inits upper end, as indicated at S, to receive the cam shaft, the parts atopposite sides of the notch 8 being widened to obtain ample bearingagainst the sides of the cam shaft. The sockets 5 project a shortdistance upon opposite sides of the heads 4 in order to obtain anextended bearmg upon the rod or bar 3. Theheads 4 are mounted to slideand to oscillate upon the rod 8, the sliding movement providing forproper spacing of the cutters and the oscillatory movement enabling thecutters to be moved to and away from the .work. A lazy tongs structure10 connects the cut-- ters so that adjustment of one of the cuttersresults in a corresponding movement of the remaining cutters so as toequally space them apart. The lazy tongs structure 10 has its elementspivotally connected to the series of cutters at their points ofcrossing. The lazy tongs structure is housed within the base. I

The cam shaft ll is mounted at its ends in the standards 2 and engagesthe notched portions 8 of the cutter heads 4 so that movement of thecamshaft in one direction advances the blades to the work and move-'ment of the cam shaft in the opposite direction carries the blades awayfrom the work. The cam shaft 11 is adapted to be operated by means of ahandle 12 which embodies spacedarms and a cross piece connecting theouter ends of such arms.

A work holder 13 is located at one end of the base and comprises acurved lever which is pivoted between its endsto one of the standards 2,a spring 14 serving to press the upper end of the lever upward, wherebyits lower end is forced downward so as to grip the Work placed betweenit and the base.

A plate 15 is located along one edge of the base at a point below theblades of the cutters and supports the work. When the machine is adaptedfor cutting buttonholes of diiferent sizes the plate 15 may haveportions cut from one edge, as indicated at 16, so as to provideportions of different widths corresponding to the various lengths ofbuttonholes to be out. By shifting the plate 15 upon the base 1 portionsmay be brought in position below the blades so as to cut buttonholes ofthe required length.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invent-ion appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merelyillustrative, and that suchchanges may be made When desired as are within-the scope of the claimsappended hereto.

Having thus described the invention What is claimed as new, is

1. In combination a support, a plurality.

of cutters mounted upon the support, each of said cutters consisting ofa head embody ing a socket, a notched portion and an extension, thelatter having the cutter proper attached thereto, means forsimultaneously moving the cutters to effect proper spacing thereof, anda shaft having a cam portion engaging the notched portions of thecutters.

to effect simultaneous movement thereof.

2. In combination a rod, a plurality oi cutters mounted upon the rod,each consisting of ahead embodying a socket through of a head having asocket, a notched portion and an extension, the latter receiving thecutter proper, lazy tongs connecting the cutters and arranged Within thebase below the said rod, means between the lazy tongs connection andbase for operating the lazy tongs to properly space the cutters, and ashaft mounted upon the base and having a cam portion entering thenotched portions of the cutters to effect simultaneous movement thereof.

4. A buttonhole cutter comprising a hollow base provided at oppositeends with standards, a rod supported at its ends in said standards, alurality of cutters mounted upon the rod, each consisting of a headhaving a socket, a notched portion and an .extenslon, the latterreceiving the cutter iproper, .a lazy-tongs arranged Withln the base andconnecting the. cutters, operating means between the lazy tongs and.base for effecting a proper spacingof the cutters.

and a shaft mounted in the standards and havinga cam portion engagingthe notched portions of. the cutters.

In testimony whereof I affix. my signature in presence of two witnesses.
